Monte-Carlo Analysis of the Nonlinear Susceptibility in Quantum Cascade Laser Structures for THz Difference Frequency Generation(OSA The Optical Society, 2015)
(VDE-Verlag, 2014)Infrared detectors for the long-wave infrared range (lwir) are of special interest due to their ability to detect blackbody radiation of objects at room temperature. Such detectors are attractive candidates for various ...
(SPIE, 2013)High temperature operation of terahertz (THz) sources based on quantum cascade lasers (QCLs) is discussed. THz QCLs are compact, powerful sources but can only operate at cryogenic temperatures. State-of-the art THz QCLs ...
(IEEE, 2007)We theoretically investigate the temperature dependence of the carrier transport in GaAs-based THz quantum cascade lasers and identify the factors restricting high-temperature operation. In this context, we compare a single- ...
